Ok don't run in compatibility mode. See here:

LOGic 9 user-defined field data is not compatible with LOGic 8. You can go from 8 to 9, but not 9 to 8. (You could use ADIF of course, but just transferring the data via Logic's backup or copying/importing the log.dbf, no).
Why not simplify things by installing LOGic 9 on the Win 7 machine -- in other words, all machines? LOGic 9 is licensed for unlimited installs by you and your immediate family :-)
Tnx & 73,
